Question

In an experiment, the population of bacteria is increasing at the rate of 100% every minute. The population is currently at 50 million.

How much was the population of bacteria 1 minute ago?

Answer 1

Answer:

2500000

Step-by-step explanation:

Rate of increasing the population of bacteria=100%

Let the population of bacteria 1minute ago be x

Then,x+(x×100/100)=50000000

Or,x+x=50000000

Or,2x=50000000

Or,x=50000000/2

Or,x=25000000
